There is growing evidence that, in addition to attacking patients’ lungs, the coronavirus also targets the central nervous system, causing adverse neurological symptoms.
As COVID-19 spreads in the U.S., there is growing interest in the role and appropriateness of chest radiographs (CXR) and computed tomography (CT) for the screening, diagnosis and management of patients with suspected or known COVID-19 infection. Contributing to this interest are limited availability of viral testing kits to date, concern for test sensitivity from earlier reports in China, and the growing number of publications describing the CXR and CT appearance in the setting of known or suspected COVID-19 infection.
Several new studies present peer-reviewed cases of COVID-19 in order to ensure that the disease is diagnosed as rapidly as possible, and thus help prevent an overwhelming spike in infections in any one place during the course of the current pandemic. Much interest has been shown in the possibility of using chest X-rays, and computed tomography (CT) scans to screen for and diagnose patients with this illness, whether suspected or confirmed.
A computerized tomography scan (CT or CAT scan) uses computers and rotating X-ray machines to create cross-sectional images of the body. These images provide more detailed information than normal X-ray images. They can show the soft tissues, blood vessels, and bones in various parts of the body.
